The hold on Coupe 60 for the US market has been put on hold, right alongside any chance of a rwd Impala. New CAFE standards are the big culprit, despite GM's current ability to equal mpg in similary powered rwd and fwd vehicles where the rwd is heftier by 400#. I don't think rwd development is dead, in fact even Subaru with Toyota's help is getting into it
Winding Road Archive Toyota/Subaru Coupe Tipped in Early Sketch but the key to the survival of rwd is smaller, lighter, greener packaging. Part of it is all the safety requirements, but todays G8 is no lighter than full-size sedans of 40-50 years ago.
